| 20090021955 | CONTROL NETWORK FOR LED-BASED LIGHTING SYSTEM IN A TRANSIT VEHICLE - A transit vehicle lighting system has a plurality of LED-based lighting fixtures for providing interior illumination. A control network comprises a plurality of slave nodes for controlling the LED-based lighting fixtures, and a master node for controlling the slave nodes. The master node may be connected to the slave nodes by a combined power/communication bus in a daisy chain fashion. The slave node may include a power regulator and a controller for providing a target current command to the power regulator, and may adjust the target current based upon temperature measurements or a recorded age of the LEDs. An optical sensor may provide automatic dimming. A reduced number of LEDs may be used in an emergency mode. The lighting fixture may include a ceiling panel fixture and a riser panel attachable by way of a hinge mechanism. | 01-22-2009 |

| 20090109306 | HIGH DYNAMIC RANGE SENSOR WITH REDUCED LINE MEMORY FOR COLOR INTERPOLATION - An image sensor has an array of pixels organized into a row and column format. Pixels are read out in a line-by-line sequence and buffered in a line image buffer. An extended dynamic range is supported by varying a column exposure time according to a periodic sequence. As a result, the pixel exposure times vary within each row. A high dynamic range is generated by combining pixel data of adjacent pixels within the same row that are of the same filter type but having different exposure times. Color interpolation is performed on the combined line data. | 04-30-2009 |
| 20090251561 | System and method for adaptive local white balance adjustment - The disclosure describes embodiments of an apparatus comprising an image sensor including a pixel array having a plurality of pixels and an automatic white balance (AWB) circuit coupled to the pixel array. The AWB circuit is used to determine a local white balance component for each pixel, determine a global white balance component for each pixel, and apply a white balance adjustment to each pixel, the applied white balance adjustment comprising a combination of the local white balance component and the global white balance component. The disclosure also describes embodiment of a process including receiving image data from each pixel in a pixel array, determining a local white balance component for the image data from each pixel, determining a global white balance component for the image data from each pixel, and applying a white balance adjustment to the image data from each pixel, the applied white balance adjustment comprising a combination of the local white balance component and the global white balance component. Other embodiments are also disclosed and claimed. | 10-08-2009 |
| 20090309995 | Automatic white balance using non-uniform averaging - The specification disclosed embodiments of an apparatus comprising an automatic white balance (AWB) circuit coupled to a pixel array to transform red, green, and blue color data obtained from each pixel into x and y chromaticity values for each pixel, determine a distance between the Planckian locus and the x and y chromaticity values for each pixel, determine a weight for each pixel based on the distance between its x and y chromaticity values and the Planckian locus, determine red, green, and blue adjustments for each pixel using its weight, and apply a white balance adjustment to the red, green and blue values obtained from each pixel. Other embodiments are also disclosed and claimed. | 12-17-2009 |

| 20090139854 | CONTROL OF ARBITRARY SCAN PATH OF A ROTATING MAGNETRON - A control system and method for controlling two motors determining the azimuthal and circumferential position of a magnetron rotating about the central axis of the sputter chamber in back of its target sputtering and capable of a nearly arbitrary scan path, e.g., with a planetary gear mechanism. A system controller periodically sends commands to the motion controller which closely controls the motors. Each command includes a command ticket, which may be one of several values. The motion controller accepts only commands having a command ticket of a different value from the immediately preceding command. One command selects a scan profile stored in the motion controller, which calculates motor signals from the selected profile. Another command instructs a dynamic homing command which interrogates sensors of the position of two rotating arms to determine if the arms in the expected positions. If not, the arms are rehomed. | 06-04-2009 |
| 20100096085 | PLASMA REACTOR WITH A CEILING ELECTRODE SUPPLY CONDUIT HAVING A SUCCESSION OF VOLTAGE DROP ELEMENTS - A bridge assembly includes an electrically insulating hollow tube or bridge having a pair of ends, the bridge being supported at one of the ends over the cylindrical side wall and being supported at the other of the ends over the electrode. The bridge assembly further includes a set of conductive rings surrounding the hollow tube and spaced from one another along the length of the bridge, and plural electrically resistive elements. Each of the resistive elements has a pair of flexible connectors, respective ones the resistive elements connected at their flexible connectors between respective pairs of the rings to form a series resistor assembly. | 04-22-2010 |

| 20090218324 | DIRECT REAL-TIME MONITORING AND FEEDBACK CONTROL OF RF PLASMA OUTPUT FOR WAFER PROCESSING - A method and apparatus for controlling power output of a capacitatively-coupled plasma are provided. A detector is disposed on the power delivery conduit carrying power to one electrode to detect fluctuations in power output to the electrode. The detector is coupled to a signal generator, which converts the RF input signal to a constant control signal. A controller adjusts power input to the RF generator by comparing the control signal to a reference. | 09-03-2009 |
